These analyses revealed that FSP1 levels were upregulated in multiple cancers compared to their corresponding normal tissues, including LUAD, LUSC, kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), kidney chromophobe (KICH), stomach adenocarcinoma (STAD), liver hepatocellular carcinoma (LIHC), and uterine corpus endometrial carcinoma (UCEC) (Fig. 4a). This evidence concerns the gene AIFM2 and uterine corpus endometrial carcinoma.
